Best fix and fall energy tariff deals UK (February 2026)

Compare the best Fix & Fall energy tariff deals (UK homes)

A Fix & Fall tariff is designed for households who want the security of fixing today, with the potential to pay less later if prices drop. These tariffs typically start with a fixed price, then move to a lower rate at a specified point (or apply a discount mechanism) if market prices fall.

In February 2026, the “best” Fix & Fall deal depends on your postcode, meter type (smart, standard, Economy 7), payment method (Direct Debit, prepay), and how much energy you use. That’s why EnergyPlus.co.uk compares a whole-of-market panel and shows you eligible options side-by-side.

What you’ll need to get accurate results

• Your postcode (to match regional network charges)
• Whether you have gas & electricity, or electricity-only
• Your meter type (smart/standard, Economy 7, prepayment)
• Your typical usage (kWh) or spend (monthly/annual)

More predictability than variable

You lock in rates for the initial period, which can help protect your household budget from sudden price rises.

Potential upside if prices drop

Unlike a standard fixed tariff, Fix & Fall designs may reduce prices later (e.g., a lower rate after a set date). Always read the tariff rules.

Clearer decision-making

Comparing unit rates, standing charges, and fees in one place makes it easier to pick the right tariff for your usage.

Good for medium-term planners

If you expect to stay put for 12 months+ and want stability, these deals can be a practical middle ground.

Often available for dual fuel

Many households can compare Fix & Fall options for gas and electricity together, potentially simplifying billing.

Fits smart-meter households

If you have a smart meter, you may see more tariff variations and clearer usage estimates when comparing.

If you’re unsure, use the comparison form to view eligible Fix & Fall tariffs alongside standard fixed and variable deals.

Typical Fix & Fall structure

1. Start on fixed rates
   You begin on a fixed unit rate and standing charge for an initial period.
2. Defined “fall” event
   The tariff includes a specific trigger such as a set date, a published benchmark change, or a supplier-defined pricing review.
3. Lower rate applies (if the rules are met)
   If conditions are met, the unit rate may reduce for the remainder of the term.
4. End of term decisions
   Near the end date, consider switching again to avoid rolling onto an expensive default tariff.

Before you choose a deal

• Confirm the “fall” rule: date-based, benchmark-based, or supplier review?
• Compare total cost: unit rates + standing charges + any fees.
• Check exit fees: what it costs to leave early if a better deal appears.
• Match your meter: Economy 7 and prepay deals can be limited.
• Payment method: Direct Debit tariffs can differ from pay-on-receipt.

When comparing in February 2026

• Use your postcode: standing charges vary by region.
• Use realistic usage: estimates change significantly with kWh.
• Look at the full term: don’t judge on the first month only.
• Note customer service factors: billing clarity, smart meter support, help options.
• Plan your next review: set a reminder 4–6 weeks before the end date.

Postcode pricing

Network costs vary by region, affecting the standing charge and sometimes unit rates. Always compare using your postcode.

Economy 7 / multi-rate meters

If you use night-time electricity (storage heaters, immersion), check day/night rates and your usage split—Fix & Fall may still be suitable, but only if the rates align.

Prepayment meters

Deal availability can be narrower. Comparing matters even more, but check eligibility and how topping up works with each supplier.

Are Fix & Fall tariffs always cheaper than a fixed tariff?

Not always. Some Fix & Fall tariffs start slightly higher than the best fixed deals, then aim to reduce later. The only reliable way to judge is by comparing all-in costs for your home, including standing charges and any fees.

Will my price definitely “fall” on a Fix & Fall deal?

No. The “fall” depends on the tariff’s terms. Some deals reduce on a set date; others rely on a benchmark or supplier review. Always read the tariff information and check the exact mechanism.

Can I switch away if I find a better deal later?

Usually yes, but you may pay an exit fee if you leave during the fixed term. Check the fee amount and whether it applies per fuel (gas/electricity).

Do Fix & Fall tariffs work with smart meters?

Often yes. Smart meters can improve accuracy of usage estimates and eligibility for certain tariffs. However, availability still depends on the supplier and your meter setup.

Is switching energy supplier disruptive?

For most households, switching is straightforward and you won’t lose supply. Your new supplier typically coordinates the switch, and you’ll just provide meter readings if requested.
